Abstract

UN APARATO DE BOMBEO DE COMBUSTIBLE DE TIPO DE DISTRIBUIDOR GIRATORIO INCLUYE UN EMBOLO DE BOMBEO PRINCIPAL 12 Y UN EMBOLO AUXILIAR 20 ACCIONABLE AL MISMO TIEMPO POR UNA LEVA. DURANTE EL MOVIMIENTO HACIA ADENTRO, EL EMBOLO DE BOMBEO DESPLAZA EL COMBUSTIBLE HACIA UNA SALIDA 15. EL EMBOLO AUXILIAR 20 DESPLAZA EL COMBUSTIBLE A UNA PERFORACION DE LANZADERA 33 QUE CONTIENE UNA LANZADERA 34 Y, DURANTE EL MOVIMIENTO HACIA ADENTRO INICIAL, SE ABRE UN PRIMER TRAYECTO DE CIRCULACION 45, 46 PARA EL DRENAJE DE LA PERFORACION 11 QUE CONTIENE EL EMBOLO DE BOMBEO, PERO SE CIERRA AL PRODUCIRSE EL MOVIMIENTO ADICIONAL DE LA LANZADERA HASTA QUE SE ABRE UN SEGUNDO TRAYECTO DE CIRCULACION 45, 41, 43. EL SEGUNDO TRAYECTO DE CIRCULACION INCLUYE UNA GARGANTA 41 QUE TIENE UN BORDE INCLINADO 42, DE MODO QUE EL AJUSTE ANGULAR DE LA LANZADERA DETERMINA LA CANTIDAD DE COMBUSTIBLE QUE SE SUMINISTRA A TRAVES DE LA SALIDA. CUENTA TAMBIEN CON UNA VALVULA 38 PARA PERMITIR DESPLAZARSE AL COMBUSTIBLE POR ACCION DEL EMBOLOAUXILIAR DE MODO QUE FLUYA A UN DRENAJE.A ROTARY DISTRIBUTOR TYPE FUEL PUMPING APPLIANCE INCLUDES A MAIN PUMP PUMP 12 AND AN AUXILIARY PUMP 20 DRIVABLE AT THE SAME TIME BY A CAM. DURING THE INWARD MOVEMENT, THE PUMP PUMP MOVES THE FUEL TOWARDS AN EXIT 15. THE AUXILIARY PUMP 20 DISPLACES THE FUEL TO A PITCH OF A SHUTTLE 33 WHICH CONTAINS A SHUTTLE INWARD, AND INWARD THE MOVEMENT INWARD. OF CIRCULATION 45, 46 FOR THE DRAINAGE OF DRILLING 11 CONTAINING THE PUMPING TANK, BUT IT IS CLOSED WHEN THE ADDITIONAL MOVEMENT OF THE SHUTTLE IS PRODUCED UNTIL A SECOND CIRCULATION PATH IS OPENED 45, 41, 43. THE SECOND CIRCULATION PATH IT INCLUDES A THROAT 41 THAT HAS A SLOPED EDGE 42, SO THAT THE ANGULAR ADJUSTMENT OF THE SHUTTLE DETERMINES THE AMOUNT OF FUEL SUPPLIED THROUGH THE OUTLET. IT ALSO HAS A 38 VALVE TO ALLOW THE FUEL TO GET AROUND BY ACTION OF THE AUXILIARY PUMP SO THAT IT FLOWS A DRAIN.
